At Meebo, Foosball is one of our favorite pastimes.  Because we're such a fun-loving bunch, we decided to host a double-elimination foosball tournament.  While looking for an online tool to help manage our foosball tourney we came across a pretty cool implementation called Challonge!  Very nicely done.  I can imagine some fun stuff with player/team profiles, stats, records, office pools.  What will you use it for?
